EMANUEL IIAGSTROM AND GUSTAF HAGSTROM, OF LINDSBORG, KANSAS.

LOCATION-INDICATOR FOR CARS.

I To all whom itmay concern:

Be it known that we, EMANUEL HAG- STROM and GUSTAF IIAGsTRoM, citizens of the United States of America, and residents of Lindsborg, county of McPherson, and State of Kansas, have invented certain new and useful Improvements in Location-In dicators for cars, of which the following is a specification.

Our invention relates to location indicators for cars, and has for its object an improved device for use in street cars for indicating street crossings, or to be used in rail- Way'coaches for indicating stations.

In the accompanying drawings, Figure 1 is an elevation of the case which contains the operating arts; Fig. 2 is an enlarged elevation With't e casing removed; Fig. 3 is a section al elevation on line 3 3 of Fig. 1; Fig. 4

is anelevation of Fig. 2 from the right hand end; Fig. 5 is an enlarged end view, corresponding to Fig. 3, of one of the rolls; Fig. 6 is an enlarged detail on line 66 of Fig. 2; Fig. 7 is an elevation of the attach- .ment which goes upon the trolley pole of a street car;flFig. 8 is a section on line 8-8 of Fig. 7; Fig. 9 is a section on line 99 of Fig. 7; Fig.710 is a perspective of the trip which 'oes on the staywire of a trolley system; Fig. llshows the system applied to a street car and using the trolley current; Fig. 12 shows'the same thing using a battery; and Fig. 13' shows the system applied to railway coaches. In Fi s. 11, 12 and 13, the ears and present a pIiances are shown in dotted lines, the full ines representing what we add to make an o erativesystem.

In the sai drawings 20 is a casing which contains the mechanism and which is provided with arwindow 21 through which the names of the streets or stations may be seen. Secured to the back of the casing are two bars 22 which support the mechanism and by which the device'may be secured to the wall of the car. Supported by a suitable frame operation the belt is wound upon roll 23, but

during ano eration is gradually transferred to roll 24; t is then returned to roll 23 by means of the crank 31 operated by hand.

On the'shafts of the rolls 23 and 24 arev gears 26 and 27 which mesh into gears 28 and Specification of Letters Patent.

29 on an intermediate shaft 30, on which shaft there is a crank 31. The crank 31 and the gear 28 are fast to the shaft 30, while the gear 29 is loose thereon. Between the portion of the frame 32 and the gear 29 is a stationary s ring case 33, in which is an ordinary cloc spring having one end fast to the case 33 and the other end fast to the loose gear 29. On the other end of the shaft of the roll 23 is a disk 34 having lugs 35 and 36 arranged in the manner best shown in Fig. 5.

Supported at a convenient place is an electro magnet 37 whose armature lever 38 carries a pin 39 adapted to engage the lugs 35 and 36 to stop the rotation of the disk 34 in the direction of the arrow of Fig. 5. The length of movement of the armature lever 38 is limited by lugs 40 and 41 (Fig. 6) on a portion 42 (Fig. 2) of the frame. The lugs 40 and 41 are held in lace by screws 80 and 81 which pass throng the slot 82 in the end of the ortion 42 of the frame. On the end of the ever 38 is a clapper 43 arranged to strike a bell 44 each time that the magnet is actuated.

In the normal position of the lever 38 the it will be stopped by contact between pin 39 and the next 1ug'36. If the magnet is not denergized so quickly, then the stoppage will occur by reason of contact between the pin 39 and the lug 35. As soon as the circuit is broken through the magnet 37 the pin 39 will slip from lug 35 to 36. These movements of the roll 23 advance the belt 25 far enough to remove one name from the window 21 and substitute another, the spacing of the names on the belt being such as to bring about this result for each operation of the magnet. It will be observed that in this operation the spring in the case 33 does not act directly upon the roll 23 which carries the disk 34, but directly upon the roll 24 and thence through the belt 25 to the roll 23. This results from the fact that the gears 28 and 29 are connected together only through the belt 25 and gears 26 and 27. The effect of this is to always keep the belt tight, one

end of the belt being fast to one roll and the other end fast to the other roll.

When a trolley system is used as shown in Figs. 11 and 12, there is secured to the trolley pole 50 a bracket 51 to which is secured a Stud or pin 52. On this pin is a sleeve 53, the inner end of which is partially cut away so as to leave a contact segment 54 adapted to engage a contact spring 55 when the sleeve is moved from its normal position. A spring 56 and collar 5'7 on pin 52, together with a stop 58 on the bracket 51 serve to normally hold the segment 54 and spring 55 out of electrical connection with each other. On the sleeve 53 is an arm 59 on which is pivoted a lever 60. A spring 61 normally holds the lever 60 against a stop pin 62. Pressure on the lever 60 toward the pin 62 while in contact therewith results in turning the sleeve 53 on the stud 52, the effect of which is to close electrical connection between segment 54 and contact spring 55. A release of the lever permits spring 56 to break this electrical connection by returning the sleeve to its normal position. A movement of the lever in the opposite direction simply results in turning the lever idly on its pivot 63. The trolley wire is shown at 64 in Fig. 11 and the stay wire at 65. This stay wire is the one ordi narily used in steadying and holding the trolley wire from swaying. On the stay wire is clamped a bracket 66 (Figs. 10 and 11) which is adapted to be engaged by the lever 60, the effect of which is to turn the sleeve 53 and close the circuit through the spring 55 and the magnet 37. These brackets 66 are l0- cated'at the places where it is desired to shift the indicator, and each shift is accompanied by an alarm sounded by the bell 44. When the current for operating the magnet 37 is taken from the wire 64: it passes through the device to ground as shown in Fig. 11. When a battery is used the arm 60 is insulated from the sleeve 53 and the circuit is completed as shown in full lines in Fig. 12. On railway coaches the circuit is completed by'a push button 45 as shown in Fig. 13. In this case the connections may be conveniently extended from car to car by attaching the wire in any suitable way to the hose for the air brake system. Or each car may be independent of each other car, in which case each car would carry its own battery and push button. As shown in Fig. 13, one battery serves for the entire train, but each car is pro vided with one or more push buttons so that the indicator may be operated by the proper em loyee at whatever place he might be.

when the indicator has run to the end it is returned to normal position by the employee turning the crank 31. In doing this the escape wheel 34 acts as a ratchet wheel, and the pin 39 acts as a pawl. By observing Fig. 5 it will be seen that the lugs 36 and 35 are tapered to points at their rear ends so that if the disk 34 should be turned by hand in the direction opposite to the arrow, the pin 39 would pass between these lugs and act as a holding pawl on a ratchet wheel.
